A spokesman for Kirsty confirmed the split after four years of marriage but told The Sun on Sunday that no one else was involved.

A source told the paper that their marriage had been on the rocks for about a year, adding that cracks started to appear after former Wasps winger Paul was forced to retire from rugby in 2011 due to injury.

They added: "Neither of them were very happy and they were rowing."

The couple met at a charity event in 1999 and set up home in Virginia Water, Surrey.

Paul proposed in the Yorkshire Dales in 2009 and they were married in Arcos de la Frontera, Spain a year later.
